Thisinvention relates generally topresses einployingicompressed air@ .1 .l c i The. primary. object of the invention. resides in the provision of an assemblageof component parts `whereby air at normal atmospheric pressure may be compressedand then transferred for the operation ef'certain die members in the manufacture of antiicial iiowers. L: l c. l i

lAnother object ofthe invention: is the provision of meanssforinducing awilow of air into a space :and .subsequently compressing said airandiinally transferring the samezto a position' for the performance of useful ivorlr.` l ,f l, i i LStill another objectiiesides in the, provision of means, directlyresponsive toi said Y air-entry inducingmeans, for cutting oil the iiow of air intoifthe' device pressingoperation: s: t 4 i A still further object is to proyide means for operating theudevice duringothe `coinpression or Working stroke, said means being oi alternative' form, thatis, the operation of one of the-forms laces the other in a position `for facilitatinglthefrestorationof the part-s to afpositionuready to aiect the com pressionof theluidgsuch as: air,eor the like. i A. still further objectiof theV invention is to provide ma reciprocatory member having associated therewith yieldable mean-s adapted to facilitate the restoration oii'saidl reciprocatory member to itsnormalposition subsequentto the compressionstrolre. n y A i.

Still Yfurther objects and ladvantagesof the invention Willbecoine apparent as the description proceeds, and in: order that the same may be better understood reference is had to the accompanying drawings forming a part ot' this specification; i

ln carrying'- out `the aforesaid objects of the invention,4 I proposed` toy provide tivo cylinders 10 and `11, thefii'form'er being termed the major cylinder and the latter theminor vis concerned, andthisis a feature of cylinder. kVlithinsaidcylinders are mounted reciprocat'ory members 12 and 13, the said memberlQ being .operated directlybyy cci'.- tain` ffootoperated mechanism', Y While tithe member .lisoperated bya duid,` such air, after-having, been subjected to` thelin- `fluence o l: saidv member 12. c In kother; Words, there is no,` directy connection bet-Weenithe reciprocatory` member ,12 and said member` 1B, in so far as coordinated mechanical structure vention. il. is l c `The broad concept of the inventionghavingbeen stated, let us `consider the detailed structural arrangementoof my device and upon reference specilically-to EF ig. :1, itiwill be notedthatll have pro'vided said cylinder 10 with a basal fiangeglnadjacent thelopen end of saidcylindenthere; being protfided a plurality offasteningderices 115 for anchoring the sameltoa table `16,.or other suitableV supporting Ameans` The top of said cylinder is closed by ahead 17 having -a depending annular flange `18 insertible in said4k cylinder, said; head lrbeing centrally `bored y"and threaded, if necessary, forthei reception of a pipe 18 Yconnectedto acheckwalve lQlxestablishing, communication with the vatmosphere at certain intervals; lntermediatenslaid pipe V1S `is disposed a T-iitting- 20 carrying ahorizontal ,pipeQl l'eadingtothe pipe 22,1 and throughV the .i series of pipes atoresaidvthe said valve 19, communicationis established between said cylinders 10 and 11 andthe atmosphere. As lshown in said :Figs "lfsai'd the incylinder 11 yis also provided with a" centrally apertured closure nlieinber "23' for the obvious purpose ofclosing the open endof saidcylinder andiiui'ther receivingthelovver extremity of said pipe22, said4 cylinder-11 being preferably secured to said cylinder-1() by means ci? a bracket 2li, orother suitable ar- Y rangement.' i

s leverting now to 4the'1reciprocatony meinbeis 12 and 13,it Will bepobserv'ed` that the y latter is provided with a. forni of guiding means, suchas the stem 25,-Wliicli" slides in the aperture 26 at4 the bottom'blosed portion of said cylinderll, the extreme lower end of said stem 25 being squared, as indicated at 27.

Said reciprocatory inje1nber V13 is further provided With` yiel'dable means .in the form of a spring-28, positioned between' `said members 13 and the bottom Oisaid cylinder 11.V The other reciprocatory member 12 is provided with a ,plunger *29,

extending downwardly 'therefromfthrough' an aperture in the top. of said table 16, the lower portion otsaid plunger being preter- 4 ably squared as indicated'at 31' and having V :be observed thatA said cables 38 andA 39jarev y rack teeth 32 cut into the face thereof, .which enmeshfwithi a gear wheel 33`mounted'on'stub gshaii'tl 34 .supported by thefyoke bracket 35.
